Inthe drawings," wherein for lthe purpose of Aillustration is shown only a preferred embodiment of this invention, the letter A may generally designate the improved dish washing apparatus which may ycomprise a trough or tub B; table C; spray receptacle D; and water dispensinfixtures E associated with the parts of t e apparatus.

The trough or tub B is preferably of any approved construction, although preferably of elongated character, including .a bottom jwall 10; end walls l2.; and side walls 13 and 14. The same-provides a relatively deep compartment 15,'and af drain conduit 16 is connected in the bottom wall 10, and leads to any suitable place, such as a sewer, the same preferably having a trap 17 therein adjacent the trough B. At the juncture of the `drain conduit 16 and the wall 10,'a socket 18 is provided adapted to detachably receive an overflow control pipe 19 which may fit in the socket 18 to act as an extension for the conduit 16,l a passageway 20 thereof being open at the top edge thereof, and the top edge 23 being-located below the upper edges of the sideand end walls 12, 13I and 14, as is illustrated in the drawings, so that the head of water inthe compartment 15 willbe relatively high, during dish washing operation, although merely by removal of theA overflow, extension 19 the entire body lof water in the compartment 15 may drain thruthe conduit 16.

It is preferred to provide a dish supporting tray 25 in the compartment 15 immedi` ately over the floor or bottom 10 thereof,l upon which the ldishes may rest as a protection .therefor against br `king when they drop into the trough for the initial cleaning operation. l

Referring to the construction of theldrain table C, the same preferably includes a vtable board or platform 27, supported inpany approved inanner by legs 28. The table body 27 is constructed to provide Aan opening 29 extending -to one end thereof, in which openof; trackand dish supporting platform V for the spray receptacle of the improved ing 29 the spray receptacle D is received, as V will be subsequently set forth. The drain table body 27 includes the drain and drying scribed.

portion 30, extending from the inner end of the opening 29 to the outer edge 31 of the table, upon which dishes pass in the final operation to. dry and drain. The table body 27 at opposite sides of the opening 29 has drain ways or side extensions 31 and 32, which at the free edges thereof are provided with anchoring lips or extensions 35, -downturned, as is clearly illustrated in the drawings, for engaging over the upper edge of the side wall 13 of the trough B, in order to anchor and support this end of the drain table on the trough B. It is to be noted that the opening 29 has an entrance at the end of the table where the lips are formed, and the longitudinal edges 37 of this opening 29 are beveled in downwardly converging relation to sup ort the oval-shaped spray re` cepta'cle bo j as will bel subsequently de- 'Ilhe table platform 27 is provided withO a lip extension 38 which projects into the opening 29 at the inner end thereof, and which is likewise adapted to project into the compartment 40 of ,the spray lre^eptacle D, and has a bevelled' edge 39a.

. C is so mounted by the legs 28 that it slopes of is providedwith from the edge 31 downwardly at a gradual incline towards the trough B, in order that water may drain from the table drying portion 30, along the ways 31 and 32 and thence into the trough compartment 15, as can readily be understood. along the opposite longitudinal edges thereguard rails or rims 42, projecting upwardly of the plane of the up` per surface of the table body 27, for the entire length thereof, in order to prevent lateral drip or drain of water from the table body 27.

As is illustrated in Figure 1 of the drawings, any of the legs 28 of the apparatus may be providedwith suitable brackets for supporting the trough B. In lieu thereof, the-trough B may be providedwith independent leg supporting means.

.Referring to the spray receptacle D, the

. same in cross section'is preferably oval, in-

cluding the oval shaped body 45, with front and rear Npreferably Ilat end walls 46 and 47, respectively having entrance and exit open` ings 48 and 49 therein. The openings 48 and 49 are preferably square, and the former opening.' is pro'videdJw/ith closure doors 50, hingedly connected by spring hinges 51 at the opposite side edges thereof, the tendency of the spring hinges being such as to maintain the doors 50 shut toA close the opening 48, and prevent splashing of water from the compartment 40: In similar manner lthe opening 49 is provided, with a'I pair of' closures 52 hingedly connected by spring hinges 53 at opposite side edges of said opening 49, the spring hinges 53 urging the doors or closures4 52 into a Shut vposition to from the wall 46 The table l The table body 27.

`close the opening 49. It-should be noted that the lower edges of the doors 5()r and 52- are spaced slightly above the lower edges of the openings 48 and 49.

The receptacle D is adapted to be placed in the opening 29 of the table body 27 and in this position the sloping side walls of the body 45 of the receptacle rest upon the beveled edges .37 facing the opening 29. The lip 38 of the tableenters thelopening 49 just below the doors 52, so that said lip 38 really projects'into the compartment 40 of the spray receptacle D, to aid in supporting the rack `55 upon which the dishes slide in their travel through the spray compartment 40.

At the front end of the receptacle D, a drain and supporting lip 57 is downturned of the receptacle D, thc same being disposed below the doors 50, to engage over the top edge of the trough wall 13, as an aid in support of the receptacle D, and to enable proper drain of the water into the trough, and prevent leaking of the same from the apparatus. The supporting lip 57 is continuous with the supporting lips 38 of the table C, above mentioned, and as illustrated in Figure 3 of the" drawings they provide an effective seal for the drain of water past the juncture between the table C and the trough B, as well as between the receptacle D and the trough B.

The spray receptacle l'D is `-so supported that the slope of the bottom thereof is from the dish drying portion 30 of the table body 27 towardsthe trough B, and adjacent the trough B a drain conduit or opening of any suitable character, such asnshown at 60 in Figure 1 of the drawings, may be provided, having connection with the trough compartment 15 fori-drain of water thereinto from the receptacle lcompartment 40.

The slide -tray 55 is horizontally supported within the compartment 40, the same comprising a plurality of parallel spaced strips 62, connected at one end by means of a cross piece 63, and they may support at their opposite ends lateral pieces 64. It is to 'be noted that the ends of these strips 62- project beyond the cross piece 63, and the ends adjacent' the cross iece 63 rest upon the lower edge of the door opening 48, whereas the opposite free ends rest upon the .projecting table platform 27 as illustrated in Figure l of the drawings. The cross piece 63 may abut the inside surface of the Jfront -wall 46 ,of the receptacle. D, to prevent movement of of the support-ing table 27 so that theeplane Y slid over the tray 55,

dishes may be readily lip 38 of thel the trough B. The plane o the 1upper surface of the tray 55 is slightly above f thru the door opening receiving portion o the table body 27. The baskets G have lugs 64a which project into the spaces'between bars 62, to guide the baskets and support them on the drain table.

Referring to the plumbing fixtures E, hot and cold water supply cocks 70 and 71 are provided for the trough B, adjacent the end wall 12, and a lateral pipe 72 extends lfrom the hot water pipe 7 3, and is connected by a suitable fitting 74 in a vertical conduit 7 5.-

Suitable upper and lower horizontal conduits 76 and 77 extend from the upper and lower ends of the vertical conduits 75, and

have spray connections in the compartment verging relation towards the tray 55. The

" thru the conduit 60' and lower conduit 77 is provided with a cross conduit 83 just belowthe rceptacle D, extending longitudinally thereof, and at its ends being upturned and providing vertical sprays 85 and 8G in the lower portion of the compartment 4i), below the tray 55. The single valve 78 controls the spray of hot water through alll of the sprays 81, 82, 85 f and 86, and hot water may be supplied to the spray receptacle D independent of hot water supply to the trough B.

From the foregoing description of this invention it is apparent that a novel type of dish washing apparatus has been provided 1n which the trough; spray cabinet; and drying table have been so relatively positloned as to enable the continuous operation of washingv dishes to take place, with facility and with eiciency. The initial cleansing operati'on takes place in the tro 1gh B, and t e dishesare preferably handledin wire baskets G. As they ,are lifted from the trough B theyare put into the spray cabinet compartment 1.1.0l thru theswinging doors 55),

and they' readily'enter the same and are placed between' the upper and lower' sets of sprays so that thedishes thereof arranged therein are individually sprayed and cleansed.'v The successive baskets are pushed intp one end'of the spray receptacle or lcabii net, D, 1 arid succeeding baskets push thesame along the rack or tray55, which -acts as a track, and the baskets of dishes are iihally' 'forced th l the exit doors 52, onto the drain and drying portionA '30 oftheplatform 27. The drain of all water during Ithe entire pro-- cedure is into the troughcompartment 15; the water from the spray cabinet draining the water' from the l49, and onto the -tion 30 along the si drain table C draining from the drying pore portions 31y and B2 which act as troughs therefor, and the water partment 15, las is readily obvious. The operation is continuousand during the washing precedure the dishes are thoroughly cleansed, sprayed, and dryed. Due to the fact that the overflow extension 19 is pro, vided, the grease'will float linto the same,

and the lower body of water remains comparatively clean to effect the initial cleansing operation in the trough B. Thus the drain keeps the water refreshed. The spray ,chamber is protected by reason of the swinging doors, and if desired single baskets of dishes may be placed, as illustrated in trough, drain means for the trough, a spray cabinet,having a bottom, a tray for the spray cabinet disposed in a plane substantially above the said bottom and the trough, said spray cabinet having anentrance opening adjacent the trough and facing the same and an exit opening at its opposite end aligning with the entrance opening and likewise disposed above said tray, neans for spraying water in said cabinet upon articles passing therethrough, a table outwardly of theexit opening of the'spray cabinet for re ceiving ,dishes as they exit from said exit opening, said table and spray cabinet bottom inclining towards and each directly extending to the trough for drain of water thereinto 2.
